FIB-E-EXTINGUISI-IER MOUNTING.

Application filed February 15, 1926. Serial No. 88,273.

Our invention relates to fire extinguishers and more particularly to a support for that type of extinguisher commonly employed in stores, oflice buildings, residences or elsewhere for emergency use. andmore particularly of a type whereina limited supply of water is contained within a tank in the presence of a sealed vial of chemical, gas producing in the presence of water, whereby when the chemical is freed by inversion of the tank, the liquid is forced from the tank and may be employed to extinguish a fire.

While extinguishers of this type are servicealole to a limited extent, they are unavailable for use when the fire occurs in proximity to them, and it is the object of our invention to provide a support or hanger for an extinguisher of this type whereby the extinguisher maybe automatically arranged to release the gas-forming liquid and put the extinguisher in service under the very conditions under which it is at present rendered useless by the conditions above named.

In accomplishing this object we have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawings, wherein Fig. 1 is a perspective view of a fire extinguisher of the type'mention-ed. illustrated in connection with our improved mounting, the parts being shown in their normal position and relation.

Referring more in detail to the drawings.

1 designates the tank of a fire extinguisher of the chemical type hereinabove specified. comprising a restricted neck 2, an upset bot tom 3 and a hose 4, including the flexible tube 5 and discharge nozzle 6. In adapting the extinguish-er to our mounting, we provide, within the upset bottom 3, a cross bar 7, to which may be applied an open hook 8 of a shelf bar or rod 9. The bar or rod 9 has swiveling. link connection 10 with a hanger rod 11 comprising an eye 12 whereby the rod and parts carried by and connected therewith may be suspended from a hook 13 projecting from a wall or other support 14. The hanger rod 11 is formed near Fig. 3 is a perspective view of the exits upper end with a loop 15 and pivotally tend about the neck of the'tank 1 and provided at its free end with a fusible link 19, adapted for attachment with a similarlink 20, on a hook 21 attached to the opposite end of the cross bar 17.

In assembling the fire. extinguisher with our improved. mounting the hook on the shelf bar 9 is appliedto the cross bar in the bottom of the tank, the hanger rod 11 arranged parallel with the tanln'the chain or like flex ible member 18 wrapped about the neck of the tank, and the fusiblelink connected to the book 21. The tank is then suspended from the wall ofthe building by application of the eye 12 of the hanger rod to the hook 13 on the building wall.v The tank when so suspended is held in upright position and may remain thus for an indefinite time, subiectto the usual method of manual op'era-. tion.

If a fire of sufficient intensity to preclude access to the extinguisher should occur in the vicinitv of the extinguisher. heat from the fire will melt the fusible link. freeing the flexible connection that holds the tank upright and permitting the tank to swing downwardly on its pivotal and swinging connection to the position illustrated in Fig. 3.

When the tank is released as described. the flexible hose will swing loose'lv and the chemical within the tank, being free to contact with the liquid therein. will generate gas to expel the liquid in the tank through the hose. thereby bringing the chemical solution into extinguishing relation with the fire. While it is impossible that the chemical solution be effectively directed to the fire in all cases, our invention will. however, render the extinguisher effective in most cases and to that extent render the extinguisher serviceable and constitute a material advantage in the use of such devices.

In Figs. 2 and 4 I have illustrated an attachment for use in connection with fire extinguishers of this type to anchor the free end of the hose and prevent its swaying into contact with walls. windows. or persons in the vicinity of the device. The attachment preferably comprises a metal clip 22 which maybe slipped over the bottom rim of the tank 1 and includes .a flexible collar 23 for receiving the nozzle on the end of the flexible hose, together with a basin 24 for initially receiving drip .from the end of the nozzle when the parts are so arranged.

What we claim and desire to secure by Letters Patent is 1. A mounting for fire extinguishers of the chemical type comprising a hanger rod, a floor bar one end of which is pivotally connected with the lower end of the rod and adapted for pivotal connection at its opposite end with the bottom of a tank, an anchoring member at the upper end of the nod for supporting a tank upright on said floor bar and including a fusible member whereby the tank may be released to permit the tank to swing to an inverted position in suspension from the hanger rod.

2. A mounting for fire extinguishers of the chemical type comprising a hanger rod, 9. floor rod pivotally connected 'with the hanger rod and adapted for anchorage to the bottom of an extinguisher tank, a cross bar pivotally connected with the hanger rod, a flexible member connected with the cross bar, and fusible members connected with the flexible connection "and with the cross bar for normally retaining the extinguisher tank in upright position.

3. A mounting for fire extinguishers of the "chemical type comprising a hanger rod having eyes at its opposite ends and a loop near its upper end, a floor bar pivotally connected with the lower eye and having an open eye at its free end for connection with an extinguisher tank, a cross bar having pivotal connection with the loop of said hanger rod, a flexible member connected with one end of the cross bar and provided with av fusible link, and a fusible link connected with the other end of the cross bar and co-operative with the link on the flexible connection to retain the extinguisher tank in upright position and supported on the floor rod for the purpose set forth.

4;. In combination with a fire extinguisher comprising a tank, a hanger member, :arranged substantially parallel with the tank, a floor member pivotally connected with the hanger member and with the tank and arranged 'transversel to the tank and ban er r 3 OLIVER. D. BUELL. HENRY J. MILLER.
